Abstract
A take-up reel sensor measures a rotation cycle of a take-up reel of a loaded tape cassette in a take-up operation. A changing rate calculating section calculates a changing rate of the rotation cycle measured by the take-up reel sensor. A type discriminating section discriminates the tape cassette as a thick hub type or a thin hub type based on the rotation cycle measured by the take-up reel sensor, while it discriminates the tape cassette as the thin hub type or a VHS-C type based on the changing rate calculated by the changing rate calculating section. A system controller conducts a high speed take-up mode suitable for the type of the tape cassette discriminated by the type discriminating section. Accordingly, the take-up mode can be controlled by employing only the rotation cycle of the take-up reel.
